High Efficiency Refrigeration with EndoCube™
Temperature-Mimicking Sensor for Commercial Refrigeration Efficiency
The Hidden Energy Waste in Refrigeration Systems
The Commercial Kitchen / Cold Room Challenge:
In commercial kitchens / cold room, refrigeration is one of the largest and least visible operating costs — quietly eroding margins every day.
Most commercial refrigerators and cold rooms are controlled by air temperature, not product temperature.
Air temperature changes quickly due to:
- Door openings
- Fan turbulence
- Defrost cycles
- Loading and unloading
But stored food and products change temperature slowly.
This mismatch causes:
- Excessive compressor cycling
- Short on/off run times
- High electrical demand
- Increased mechanical wear
- Unstable product temperatures
In many systems, energy is wasted not on cooling — but on unnecessary cycling.
What Operators and Facility Owners Want
As cold room operators, retailers, and facility managers, you are looking for:
- Lower refrigeration energy consumption
- More stable product temperatures
- Reduced compressor wear and breakdowns
- Fast ROI without replacing equipment
- Simple, low-risk retrofit solutions
You want refrigeration to behave more intelligently — without electronics, software, or reprogramming.
“ Most refrigerators use the same signal to control the compressor that they’ve been using for the past 100 years…air temperature. But don’t we buy refrigeration to cool products, not air? ”
- Harry Banham, Refrigeration Engineer and Inventor of the EndoCube”.
EndoCube™ — A Smarter Refrigeration Control Solution
EndoCube™ is a passive, temperature-mimicking thermal mass device designed to optimise how refrigeration systems respond to temperature.
Instead of letting the thermostat react to fast-changing air temperature, EndoCube:
- Mimics the thermal behaviour of stored food and products
- Smooths short-term temperature spikes
- Forces the system to respond to real thermal load
Built for reliability and retrofit simplicity:
- No electronics
- No moving parts
- No power supply
- No maintenance
EndoCube works purely on thermal physics, making it durable and ideal for portfolio-wide deployment.

How EndoCube™ Works
EndoCube improves refrigeration efficiency by correcting thermostat behaviour, not by changing cooling capacity.
1) Thermal Mass Correction
EndoCube is installed directly over or next to the thermostat probe.
Its internal phase-change compound:
- Absorbs and releases heat like real products
- Dampens rapid air-temperature fluctuations
- Prevents false cooling calls
The thermostat effectively “believes” it is measuring product temperature, not air temperature.
2) Reduced Compressor Cycling
With smoother sensing:
- Short cycling is eliminated
- Compressor runs are longer and more stable
- Start-stop events drop dramatically
Field data commonly shows:
- Compressor cycling reduced by 50–65%
- Typical daily cycles reduced from ~40–50 to ~12–18
3) Improved Energy Efficiency & Stability
Fewer cycles mean:
- Lower start-up energy losses
- Reduced inrush current
- More efficient steady-state operation
- Better humidity and temperature stability
Cooling performance is unchanged — but energy use drops.
Proof of Functionality: How We Know It Works
Results from Singapore during a 48h trial in a walk-in chiller:
In the 24-hour window each
- The number of cooling cycles reduced by 58% after installing Endocube.
- The energy consumption reduced by 16.66%

The Set-up of the Test
Why Fewer Cycles Save Energy and Equipment
When compressor cycling is reduced:
- Electrical demand drops
- Mechanical stress decreases
- Motor windings run cooler
- Contactors and relays last longer
This results in:
- Lower operating costs
- Fewer breakdowns
- Extended compressor life
- Reduced maintenance and downtime
EndoCube delivers energy savings + asset protection in one retrofit.
How Penta Gard Is Applied
Penta Gard is applied like a conventional water-based coating:
- Surface preparation and cleaning
- Application by brush, roller, or spray
- Ambient curing with no special heat treatment
Typical application details:
- Coverage: ~25–30 m² per 14 kg
- Matte, non-gloss finish
- Can be applied over existing waterproof coatings if required
How EndoCube™ Is Installed
Installation is fast and simple:
- Mounted directly over the thermostat sensor
- No wiring or system reprogramming
- Often installed without shutting down the unit
- Typical installation time: a few minutes per unit
Once installed, the system immediately begins operating more efficiently.
